TRANSPARENT, lLDlliTG, RAL'NJPROOF W'XNDO'W SCREEN.

Application filed July 12,

My present invention relates to transparent, folding, rain-proof window screens and the principal object of the `invention is to provide a window screen `of the type described which can be used inside the usual window sash, and which whenfolded and in position will not interfere with the raising` and lowering' of thesash, andV which when the sash is raised and the screen opened, will perform all the functions of an ordinary window screen and in addition exclude the weather suchf as rain or snow without obstructing the view from the window or intertering with ventilation.

Tothis end my invention conteinpla'tesa major frame of a height not greater than one-half the height of a window sash. The side edges of this frame are grooved to receive tongued members or keepers adapted to be secured to the inside of the window frame and next to the lowerl sash. By varying the lateral extent of the keepers, the frame may be made to fit any size window, the frame remaining standard. @n the inside of this frame at each iside thereof, I provide triangular side wings, pivoted on perpendicular pins at top and bottom thereof, so that they cannot be swung outwardly beyond a plane at right angles to the plane of the main traine. These wings carry glass.

Tothe top of the main frame is secured asuppleinental frame as by hinges, which frame likewise carries glass, and is adapted to rest upon the hypotenuse of the triangu- `lar wings, and make a joint therewith. To the bottom of this frame is hinged a screen carrying frame, adapted to occupy `a horizontal position, its short side edges lying inside the side wings. its unattached longi` tudinal edge overlying' and engaging the main frame. y

The'various parts are so proportioned that the whole may be folded sopas to be included between two planes including; the front and rear faces ofthe main frame. l p

lThe invention further consists inthe novel arrangement.V construction and combination of parts herein shown and described.

p In the embodiment illustrated:

liig. e; is a viewv similar to that of Fig. 3 showing the device used in the top window sash. i 1 Fig. 5 is a frag-mental sectional View showi the device folded. 4 i Fig. 6 is a fragglnental sectional View showing` the method of hinging.

Fig: is a detail partly in section showing the hinge pins. Y

Fig. 8 is a further detail. Referring' with particularit-y to the drawings, I have shown at l a main frame `of wood or other desirable material of substantially rectangular shape of a height not more than one-halfthe hein'ht of a window sash.

The reason for this is that it may be desirable to use two of the devices ina single window sash as shown in 3;

The lateral edges ofthe traine are grooved as at 2 in order to receive the tongues of the keeper element 3 whichis secured to thefwindow frame 4L and neiitthe window sash 5.

It is desirable that the keeper 3 extendup the entire height of the window frame, so that the device'niaybefuscd at any level. Stops 6 are provided to hold or retain the deviceat any position on the keepers.

Countersunk into the mainframe lare bearingblocks which receive the hinge pins 8 ofside wings 9. Similar provision is made for pins at the bottoni of the side wings.

These wings are preferably of triangular shape, the longer leg adjacent the rightangle lying next the :traine l. Obviously., the wings 9 may be made of any desirable material, but I have found it convenient uto construct the saine of sheet material such as aluminum. ln this form the `wings proper consist of three equal thicknesses of metal, riveted together, the center thicknessbeing` of'less lateral extent than its neighbors. A piecel of glass conforiningto the wing shape and of a thickness equal to that of the wing frame is held between the two outside metal strips.

The short leg` or'base of the wings Qyis provided with a downwardly projecting eXtension 10 which serves a purpose to be described later. It will be noted that the hinge pins of the side wings are located very nearthe inside edge of the main frame l. so that when the wings are swung out-ward to the open position, they will not go beyond a plane at llatter .pulledintoavard the main traine. Tspring.catch 2O at,the bottoin of' thecinain frame `.secures .the front e window so that `its right angles to the face of the main franie.

To the top of the main traine 1 and at the outer .edge thereof, I hinge a Window consistingola skeleton framework 11 inade substantially as in the case of the triangular side v Wings, eXcept that this framework l1 `is of` rectangular shape. The "hinges are sliown at 12 countersunk `into the 4main traine `1. The vertical portions of the framework 11 ot the front Window are provided with angular flanges 13 which when in opened out position engage the outside ,of lthe side ovinos. This eiectively..prevents ,swinging out of the Wings beyond the point desired and at the saine time makes a Water-tight and insecttight `joint between the parts.

To the ,bottoni ott-he front .window 11, I hinge a bottom 14 carrying a screen 15. The inner llongitudinal `portion ot ,the bottom is provided with a flange 1G which overlies Vthe @bottom longitudinal ot the .main traine 1 and secures the parts in this position. It is to be noted that the over-all length of the screen bottoni istless `than the over-all `length `of ,fthe front Window '1l and lits snugly ibe- -tween thetopenedont side wings. The -verytical components of the `front window iframework 11 lie alongr the hypotenusal `edge of the side wings. Y

\ As above described, iit Will rbe seen that a transparent, .folding, Weather-proof Window `screen has been provided. which is also insect-proof 1n that all its Joints `are snugly fitting. Atfthelsame timethe .device neither obstruetsthe view fromthe wndowor inter `feres with ventilation.

, I have .found it desirable to provide a liront i late 17 set lintothe `bottom ot the vmain traine 1 which will'earry `the bottoni hinge pinsof the side Wings. This plate is perforated Vas `at18.` which apertures are coveredv with screening `19. This provides a ,lesser degree `of ventilation for the Window than ,when `the fdevice is opened Vout `and in Some `instances 'is `rnost desirable.

In `order tto fold lthe device, :the Kflange y16 of the screened bottom 14, is raised and pushed out. This lifts theifront window 1:1 from the `side .wings and permits tthe side .wings to tbe svvungr 'inwardly about their pivotwpins'to afpointso that the downwardly projecting `extension 10 engages the ,plate t7. llhe thicknesses ot plate 17 .and the -wingfranies.are so `proportioned,that when -fhe extension .10 engages-.the plate, -the plane of Ethe Irvingwill` substantially coincide with the ,plane 4ofthe plate and main traine.`

The above .operation having been `'coinpleted, thescreened bottom 14 is sivungnp- Avardly-againstfthe -frontavindow `11; an d the A `outside plane .substantially coincides with `theoutside plane ofthe main frame. `The twill Window from its spring catch 20. Theront -windowand screened bottom are pushed out- Wardly farenough `for the sidewings to be swung out. The `.front window is now lowered into engagement with the `h vpotenose of the side Wings, the `dances 13 overlying the outside ofthe Wing. Thescreened `bottom-is now dropped into Iplace., its flange overlying the plateul? and the AWhole is secure.

In using the device it will be apparent that Ina-ny useful combinations may `be made. For instance, if only a single `one 1s :to be usedlit may occupy `the lower half of fthe lower sash or upper halt of :the `upper sash. If the upper location is desired, the devicelmay loe held in this position `byrneans Lof the 4appropriate stop "6.

`Whereit is desired to completely7 raise the .loweravindow frame, two ofthe devices may be made use of, one resting on top Lol? the `other (see Fig. 3).

In all cases, it will be ,noted that when `the device is folded. the `window frame ma)r fbe raised 1er lowered Without interference. i

The `parts are so proportioned ythat lwhen in opened outposition, no `part of the device project beyond theouter bnildingavall line.

Whatisclairned is: i 1. A ,folding Window screen comprising a -inain dining-triangular sidewings vertically hinged thereto atfeach side thereof.` a trent window -hinged at the top -thereotsaid windowcarrying a hinged and screened bottom,

...engageable With and resting on the ymain frame.and-betweenythe side wings. i

E2. A `ioldinpfWindow screen comprising a Amain frame, `triangularside Wings vertically hinged thereto at each side thereof.thc plane `of the sidewings being;r substantiallyY `atright angles tothe plane of the main jfframe, a firent-Windowhinged-to the top of the main frame and resting upon thehypotennse of eachside wing, and a screened horizontal bottom hinged tothe bottom ofi-the `rtfront window and lyingbetiveen theside `Wings.

3. A folding window screen comprisingr a. main frame, triangular sidewings vertically hinged theretoV at eachside thereoixthe plane of the sideavings being substantially at `right angles to the plane of the VInain frame, in

front window hinged" to the top of .thermain frame and resting upon the hypotenuse of each side Wing, and a, screened horizontal bottom hinged to the bottom of the front Window and lying between the side Wings, said front Window having angular flanges at its lateral edges engaging the outside of the side Wings.

4. A folded window` screen comprising a main frame., side Wings vertically hinged 'i thereto, a :E1-ont window horizontally hinged thereto, a screened bottom horizontally hinged to the bottom of the front Window, the bottom lying between the front Window and the side Wings, the outer plane of the front Window being substantially liush with the outer plane of the main frame, the inner plane of the side wings being substantially Hush With the inner plane of the main frame. In testimony whereof, I atix my signature.
